During a high school field hockey game, every spectator placed his or her ticket stub into one of several containers. After the game, the coach chose sixteen people to march in the victory parade. What is the sample in this situation? Choose the correct answer below.

The ticket stubs

The field hockey game spectators

The coach

The sixteen people to march in the victory parade

The sixteen people to March in the sportsmanship parade

Step-by-step explanation:

A sample refers to a smaller, manageable version of a larger group. It is a subset containing the characteristics of a larger  population.  

A sample should represent the population as a whole and not reflect any bias toward a specific attribute.

Since the coach chose 16 people to March in the sportsmanship parade, the sample in this situation, The sixteen people to March in the sportsmanship parade is the sample

  Option D is the correct answer.

Explanation:

 By Pythagoras theorem  we have

               Hypotenuse² = Base² + Perpendicular²

 Here hypotenuse = 7 mm

 Let us consider other leg length given as base length

 Base = 3 mm

 So we have

                     7² = 3² + Perpendicular²

            Perpendicular² = 40

            Perpendicular = 6.3 mm

 Other leg is 6.3 mm long.

  Option D is the correct answer.
